But Ariana Grande has refused to give too much away while talking to us about THOSE nights with Niall Horan.

The 21-year-old pop princess admitted she did find the Irish hunk "super nice" when they spent time together earlier this week, one night she ended up at his Hertfordshire home and another night he went back to her hotel, but wouldn't say whether they're dating or not.

But Ariana did joke that since that evening some people have even suggested she could be pregnant with Niall's TWINS!! What on earth happened that night?

When asked at Capital's Summertime Ball about people questioning whether she and Niall are dating, she told Mirror Celebs: "Well, that's just society. She must be pregnant, she must be expecting twins! But he's really nice.

"I'm honestly so tired of talking about dating and my love life and everything.

"I'm kinda doing my thing right now.

"People don't ask the men. It's like, 'Is that the only thing we have to talk about? Is that the only thing women are relevant for is their relationship with men?' No.

"We're absolutely perfectly fine on our own and we can talk about our music, our work, our kick-ass tours around the world. Why don't we talk about that as opposed to who we're currently flirting with?"

Was that an admittance that she HAS been flirting with Niall?? Mmm, interesting.

While Ariana didn't give loads away about her night with the 21-year-old 1D star, she did admit to having a "really fun" time.

Speaking about her time in the UK, she added: "It's honestly been so fun being in the UK. I had my show and went dancing with my dancers.

"There were cool clowns [at Cirque] and people with weird baby heads on, it was really fun.

"My friend Fredo is really close with Niall and he came to my show in London, I met him there, he was super nice.

"We then all went over [to Niall's] for a game night, it was really fun."
